Transformation of B Lymphocytes by SV40, a small DNA tumor virus

, 2012
For decades we have assessed the risk to humans by the monkey virus SV40, through studies in animal models and humans. While there is increase in the accumulation of opinions over its DNA sequence prevalence in certain human cancers, especially non ...

Rapid identification and differentiation of the vaccine strain Rac H from EHV 1 field isolates using a non-radioactive DNA probe [PDF]

, 1992
A method for rapid differentiation between the EHV 1 live vaccine strain Rac H and field isolates is described. Total DNA was isolated from virus-infected small scale cell cultures.

Cell-free (RNA) and cell-associated (DNA) HIV-1 and postnatal transmission through breastfeeding [PDF]

, 2012
<p>Introduction - Transmission through breastfeeding remains important for mother-to-child transmission (MTCT) in resource-limited settings. We quantify the relationship between cell-free (RNA) and cell-associated (DNA) shedding of HIV-1 virus in ...

A DNA virus of Drosophila.

PLoS ONE, 2011
Little is known about the viruses infecting most species. Even in groups as well-studied as Drosophila, only a handful of viruses have been well-characterized.

MiR‐513a promotes human erythroid differentiation by modulating c‐Jun

FEBS Open Bio, EarlyView.
During early human erythropoiesis, miR‐513a promoted erythroid differentiation in primary human CD34+ hematopoietic stem‐progenitor cells and human TF‐1 erythroleukemic cells by indirectly decreasing c‐Jun and phospho‐c‐Jun expression, which are associated with increased GATA1 expression.

Complexities associated with expression of Epstein-Barr virus (EBV) lytic origins of DNA replication.

, 2007
EBV has two lytic origins (oriLyt) of DNA replication lying at divergent sites on the viral genome within a duplicated sequence (DS). The latter contains potential hairpin loops, ‘hinge’ elements and the promoters for transcripts from viral genes BHLF1 ...

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

FEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Footprinting of Chlorella virus DNA ligase bound at a nick in duplex DNA

, 1999
The 298-amino acid ATP-dependent DNA ligase of Chlorella virus PBCV-1 is the smallest eukaryotic DNA ligase known. The enzyme has intrinsic specificity for binding to nicked duplex DNA.

Vaccinia virus replication is not affected by APOBEC3 family members

, 2006
Background: The APOBEC3G protein represents a novel innate defense mechanism against retroviral infection. It facilitates the deamination of the cytosine residues in the single stranded cDNA intermediate during early steps of retroviral infection.

YIPFα1A expression is regulated by multilayered molecular mechanisms

FEBS Open Bio, EarlyView.
YIPFα1A, a five‐pass Golgi protein, is regulated at multiple layers. (1) Rare‐codon enrichment drives translation‐coupled mRNA decay. (2) A proximal 3′‐UTR element stabilizes mRNA. (3) A distal 3′‐UTR element included by alternate poly(A) site usage represses translation, which can be overridden by the proximal 3′‐UTR element.
